Apparatus made in accordance with the invention comprises a guide, areciprocatf i'or feedingthe reciprocating member 'towards the surface ofthe rail, a block or the like mounted on the reciprocating member andadapted to reciprocate therewith and carry on its under face a file,shaping or planiir tool or the like.

the continuing stroke abrading'the surface while on the return strokethe block is liftedfrom the rail and thecontinuing stroke permitting thefile to return to the initial position without rubbing on the surface.and wearing out the abrading' surface of the file, and means foradjustingand locking the file to'suit varying angles of'incli'nation ofthe rail surface.

a is a .box mounted onthe frame I) of a trolley or the like immediatelyover a rail and parallel therewith. In the box is disposed a guide 03.Between the box and the guide are springs e and feed screws f so thatthe height of the guide with respect .to the rail and consequently thepressure of the file 05am, of-1 101 Montgomery Road, "She1iield, in the111g member mounted in the guide, means I i 7 upper .or lowershoulder-formlng end of the g' or other tool" on thesurface of the railcan be regulated 1 Within the guide is mounted a shaped'r'eciprocablememberh withan lnclined under surface ;"on eac'h side and at each end ofthereciprocable member are disposed guide plates j, j each with'aninclined slot la- Underthe reciprocable member and supported by'pins m,m work; 111g in the inclined slots is a'block n h'aving an incl nedsurface to couch {with the inclined surface of the reciprocable memberand a surface parallel with the rail and carrying a file g or abradingtool. The re:

ciprocable member his'provided in its'inclined side with-an elongatedrecess, while the block a is'provided with a projection 0 extending intosaid recess but of shorter length than therecess' so as to permitmovement of theblock 'relatively'to the reciprocable member in'eitherdirection until the ingsformedjby end plates 1', 1'. The end plates 7',r carrying the base 9 are secured to the block. a by set screws n npassing through openings in the brackets 1' and threaded into the endsof the block 11 as.

shown in Figs. 1- and 4; and by reason" of the concave under face of theblock at and'partly .curvedj upperface of the base p provided for thepurpose as shown in Fig. 3, the base p carrying the file g can be tiltedif desired to suit varying anglesof inclination of the rail surface andlocked or secured in the deconnecting-rod s to a disk or crank t whichis adapted tofreceiverotary motion either from a motor'uas shown o'r byany suitable power. 41,4) are pads of rubber'to take the shock betweenthe stop-shoulders and the ends of the recess in the reciprocablemember.

In operation, assuming the block a to be in its elevated position, thatis, with its pins m occupying the higher ends of the slots in the guideplates y', the higher stop shoulder on the projection 0 of the blockwill be in engagement with the higher end of the recess in the inclinedside of the reciprocable member h, as shown for instance in Fig. 1.During the first part of the rotary motion of the disk 25 towards theleft, the block a,

by reason of the connecting rod 8, will be caused to slide relatively tothe reciprocable member h so that its pins m will ride down the inclinedsides of the slots until the lower stop shoulder of the projection 0 ofthe block abuts against the lower end of the recess in the reciprocablemember, at which time the file 9 will be in contact with the rail, itbeing understood. that the block a is carried into said position verysoon after the disk It has begun its rotary motion, the cont1nuation ofsuch motion carryingthe reciprocable member ft along with the block auntil the crank pin of the disk 6. has reached its extreme position atthe left of the axis of the disk. The continued or return rotary motionof the disk will then first pull'the blockit sothat its pins mwill rideupward infthe slots /t', ,thus raising the file out of contact with therail, and bringing the upper stop shoulder on the blockinto contact withthe upper end of the recess in the reciprocablemember h, whereupon. saidmemher is carried along with the block at until the crank pin of thedisk t arrives at its extreme position at the right of the axis of thedisk, as shown in Fig. l, sothatthe block a is again in its startingposition.

This apparatus can be made to machine the rail perfectly level or at anangle to suit the old existing rail by adjusting the swivelling base 79of the block a.

If desired a spring to may be attached to one of the guide plates j andconnected to a pin m on the block to ensure same riding up the fullextent of the inclined slot is, it being understood, of course, that theresistance to. movement of the member it due to the friction betweenthis member and the guided is greater than the resistance to movement ofthe member on due to the friction between this latter member and themember it plus the resistance of the spring w.

What I claim and desire to ters Patent I 1. Apparatus for filing,shaping and planing the surface of tramway and other rails comprisinga'guide, a reciprocating member mounted in the guide, means for feedingthe reciprocating member towards the surface of the rail, a blockmounted on the reciprocating member and adapted to secure by Letreciprocate therewith and carry a tool, the connection between thereciprocating memher and block permitting a certain lost motion, thearrangement being such, that on the forward motion the block and toolare pressed against the rail, the continuing stroke engaging the surfacewhile on the return stroke the block and tool are lifted from the railand the continuing stroke returning the block and tool to initialposition without engaging the surface and means for adjusting andlockingthe tool to suit varying angles of inclination of the railsurface. i

2. An apparatus-of the class described, comprising a guide, a memberreciprocable in said guide, a tool block carried by said reciprocablemember, cooperating means carried by said reciprocable member and blockwhereby the block is movable independently of the reciprocable member,and means for moving said block thereby to reciprocate said memberduring a portion of the movement of the block.

An apparatus of the class described,

, comprising a guide, a member reciprocable inv said guide, a tool blockcarried b said reciprocable member and adapted to reciprocate therewithand independently thereof, means for reciprocating said block, andcooperating means carried bysaid reciprocable member and block andadapted to raise theblock during its independent reciprocation in onedirection and to lower the block during its independent reciprocation inthe opposite direction. a

l.- An apparatus of the class described, comprising a guide, a memberreciprocable in said guide, a tool block carried by said reciprocablemember and adapted to reciprocate therewith and independently thereof,means for reciprocating said block, and co- 5 operating means carried bysaid reciprocable member and blockwhereby the block is reciprocated.independently of the reciprocable member during the firstpart of its reciprocation in either direction and the recip rocablemember and block are moved together-during the latter part ofthereciprocatory movement.

In testimony whereof I have signed my name to this specification. I
